WORKING TIME CALCULATOR Filed Dec. 20, 1956 2 Sheets-Sheet 2 ATTORNE KS United States Patent @fliee 2,961,157 WORKING TIME CALCULATOR Berino P. Sunico, 1515 E. Long St., Columbus, Ohio Filed Dec. 20, 1956, Ser. No. 629,716 '1 Claim. (Cl. 235-83) This invention relates to an improved disc type elapsed time calculator, especially for use by timekeepers for calculating the straight and overtime pay of workmen.

The primary object of the invention is to provide a more practical, efiicient, and more quickly and easily usable device of this kind which is operable for showing elapsed time periods, such as working time, as effected by times out, such as for tardiness, lunch and supper periods, and periods of time having special pay significance, such as overtime and night-differential working time, for which extra working pay is applicable, and the relation thereof to distinct working shifts, whereby a timekeeper can accurately calculate net total elapsed time and the pay applicable thereto for a workman.

Another object of the invention is to provide a calcu later of the character indicated, which can be made in well-finished, rugged, and serviceable forms at relatively low cost, and is highly satisfactory and acceptable for the purpose intended.

These together with other objects and advantages which will become apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout the several views, and in which:

Figure 8 is an enlarged vertical longitudinal section taken substantially on the plane of line 8-8 of Figure '7; and

Figure 9 is an enlarged fragmentary plan view showing a scale incorporated on the disc of the calculator.

Referring to the drawings in detail, the illustrated calculator, indicated generally at 10, comprises a circular disc 12, a lower or first sector plate 14, and an upper or second sector plate 16, and a radial indicator arm 18. The disc, the sector plates, and the indicator arm may be constructed of any suitable materials, such as plastic, and light weight metal, such as aluminum.

As most clearly seen in Figure 2, the disc 12 has, a central opening 20 which is aligned with an opening 22 the radially inward end or apex portion 24 of the lower sector plate 14, see Figure 5, the opening 22 being located at the interseetign of the radial side edges 26 and 23 of the sector plate 14. The upper sector plate 16 has in its apex portion 33 and at the intersection of its radial side edges 30 and '32, an opening 34 which is aligned with the opening 20 of the disc 12.

The indicator arm 18, see Figure 7, comprises an elongated flat bar or plate 36 having in its radially inward end a central opening 38' which is aligned with the open 2,961,157 Patented Nov. 22, 1960 ings 20, 22 and 34, and having in its radially outward end, in alignment with the longitudinal axis of the arm 18, a right opening or window 40, having on its opposite ends aligned inner and outer pointers 42 and 44. The indicator arm 18 has therein two longitudinally aligned and spaced inner and outer holes 46 and 48, whose purposes are hereinafter described in detail. The indicator arm 18 has on its upper surface, outwardly of the outer pointer 44, indicia 50 designating time out, that is, time for which a workman is not to be paid, and inwardly of the inner pointer 42, indicia 52 indicating hours Worked.

The lower sector plate 14 is engaged with the underside 54 of the disc 12, the upper sector plate 16 is engaged with the upper surface 56 of the disc 12, and the indicator arm 18 is engaged with the upper surface 57 of the upper sector plate 16, with a pivot pin 55 extending through the openings 38, 34, 20 and 22, respectively.

The pivot pin 55 has an enlarged head 60 on its upper end and a reduced threaded portion 64 on its lower end below the lower sector plate 14. Circumposed on the pivot pin 55 and compressed between the head 60 and the upper surface of the indicator arm 18 is a convex spring washer 62. Another convex washer 58 is circumposed on the threaded portion 64 and is compressed between the underside of the lower sector plate 14 and a retaining nut 66 threaded on the portion 64.

The disc 12 has on its upper surface 56 a full circular scale, indicated generally at 68, extending around the peripheral edge 70 of the disc 12, which is divided into twenty-four hour segments, in two groups of twelve each, each of which is numbered from one to twelve, and separated by midnight and noon marks 74 and 76, respectively. Each of the hour segments 72 is divided into sixty minutes, see Figure 9, for example. Also on the upper surface 56 of the disc 12, and concentrically spaced inwardly from the scale 68, is a shift indicating ring, indicated generally at 78, indicating the number of work shifts in a single twenty-four hour period. The ring 78 is circumferentially divided into a first shift segment 80, which extends from 8 oclock in the morning until 5 oclock in the evening, on the scale 68, and is distinguished by a predetermined color. The second shift segment 82 extends from 5 oclock in the evening until 1 oclock in the morning and is distinguished by another color. The third shif segment 84 extends from 1 oclock until 8 oclock in the morning and is identified by a still further color. The shaft indicating ring 78 is in alignment with and is Visible through the outer hole 48 of the indicator arm 18, for a purpose hereinafter described.

Concentrically spaced within the ring 78 and on the upper surface of the disc 12 is a pay differential indicating ring, indicated generally at 86, which is divided into a semi-circular segment 88, identified by a particular color, and indicating daytime hours of a twenty-four hour period, and a semi-circular segment 90, which is distinguished by a different color, and identifies that portion of a day when night-differential pay is to be paid to a workman working during such hours. The daytime segment 88 extends, relative to the scale 68, from 6 oclock in the morning to 6 oclock in the evening, and the night-differential pay segment 99 extends from 6 oclock in the evening to 6 oclock in the morning relative to the scale 68. The inner ring 86 is aligned with and is visible through the inner hole 46 of the indicator arm 18.

The lower sector plate 14 has a radius greater than that of the disc 12 and has a peripheral edge portion 92 which reaches radially outwardly beyond the peripheral edge 7% of the disc 12, in concentric relationship thereto, and preferably has a circumferential width equal to six hour divisions of the disc scale 68. The peripheral edge portion 92 has thereon a scale 96, similar to the scale 68 on the disc 12.

The lower sector plate scale 96 has extending from the side edge 26 of the sector plate 14 to the first division mark 100 of the scale 96, a distinctly colored late indicating portion 98, indicating any late starting time of any given shift that a workman works. Extending from the mark 199 is a worked time indicating portion 102, reaching across four divisions of the scale 96. Extending from the other side edge 28 of the sector plate 14 to a mark 101, at the adjacent end of the portion 102, is a one-hour lunch-hour indicatingportion 104, which is distinctly colored.

The upper sector plate 16 has a circumferential Width of preferably eight and one-half hour divisions of the disc scale 68, and a radius less than that of the disc 12 and on a peripheral edge 106 of the upper sector plate 16 on the upper surface thereof is a scale 110. At the radial side edge 30 of the upper sector plate 16 and extending radially outwardly from the peripheral edge 106 is a pointer 112. The scale 110 is divided into a segment 114 equal to four-hour divisions of the disc scale 63, and a four-hour segment 116, and is of a dilferent color from the segment 114. The inward half-hour division of the segment 116 may be distinctly colored to define a suppertime period, as indicated at 117. The segment 114 is composed of divisions numbered from five through eight, and the segment 116 is composed of divisions numbered from eight through twelve, representing numbers of hours worked. The segment 116 indicates overtime Work beyond a period of eight hours. The upper sector plate 16 has thereon an outer arc of concentric holes 118 which are aligned with and expose the outer ring 78, which are identified as three-shift indicators, so that a timekeeper may readily determine which of the three shifts, indicated on the ring 78, he is calculating time on. Concentrically spaced inwardly from the holes 118 is an inner arc of circumferentially spaced holes 120 which are alignable with and expose the inner ring 86, and serve as indicators for night-differential pay portions of a day worked. The holes 46 and 48 of the indicator arm 18 are adapted to be registered with holes 120 and 118, respectively, when the indicator arm 18 is correspondingly positioned.

As most clearly seen in Figure 1, the inner pointer 42 of the opening 40 of the indicator arm 18 terminates at the peripheral edge 106 of the upper sector plate 16, and the outer pointer 44 terminates at the peripheral edge '70 of the disc 12.

Assuming that on a given day, as shown by a workmans time card, the workman is supposed to start work at 7:00 a.m., during the first shift, but arrives one hour late, and takes one hour 011 for lunch, and would normally quit work at 4:00 p.m., but on this particular day works instead until 7 pm. and takes one-half hour off for supper, the calculator would be operated in the following manner:

Since the workman arrived to work one hour late be yond the set starting hour of 7 oclock, indicated by the mark 100 on the lower sector plate scale 96 aligned with the number eight on the disc scale 68, and with the segment 98 extending from the number seven on the scale 68. This informs the timekeeper that the workman was one hour late so that the timekeeper may make an appropriate entry on whatever records he keeps. The sector plate 16 is then rotated so that the side edge 30 thereof and the pointer 112 thereof are aligned with the side edge 28 of the lower sector plate 14, under the assumption that the workman will take a one-hour lunch period. However, if the lunch period actually taken is less than one hour, the side edge 30 of the upper sector plate 16 is ad usted to put the pointer 112 on the proper part of the segment 104 of the scale 96. The arm 18 is then rotated so that the outer pointer 44 is in alignment with the number seven on the disc scale 68, indicating 7:00 p.m., as the time when the workman quit working. "111$ upper sector plate 16 is then rotated counterclockwise for a distance equal to one-half hour, to compensate for the supper period. When the outer pointer 44 of the arm 18 is disposed in alignment with the number seven the outer pointer 44 of the arm 18 is disposed in alignment with the number seven on the scale 63, the inner pointer 42 of the indicator arm 18 will be in alignment with the number on the upper sector plate scale segment 110, which shows that the workman has worked ten and one-half hours. Inasmuch as this number appears in the segment 11%) of the scale 106, which signifies overtime pay, the timekeeper can immediately adjust his records to show the amount of over-time worked in excess of the normal working day, assuming that the length of the working day is eight hours, so that the workman would be paid for two and one half hours overtime.

When work periods in the second and third" shifts are being calculated, the timekeeper by observing the locations of the segments of the rings 78 and 86 on the disc scale 68 is immediately apprised that he is calculating work during a period of time when night diiferential pay is involved.

The foregoing is considered as illustrative only of the principles of the invention. Since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, as fall within the scope of the appended claim.

What is claimed as new is as follows:

An elapsed time calculator consisting of a circulu disc, a lower sector plate at the underside of said disc, an upper sector plate at the upper side of the disc, and a radial indicator arm at'the upper side of said upper sector plate, common central pivot means on said disc connecting said disc, said arm, and said plates together for rotation relative to each other, said disc and said plates having peripheral edges which are concentric with respect to each other, the peripheral edge of the lower sector plate reaching radially outwardly beyond the peripheral edge of the disc, the peripheral edge of the upper sector plate being spaced radially inwardly from the peripheral edge of the disc, said indicator arm having an inner end mounted on said pivot means and an outer end reaching to the peripheral edge of said discs, and functionally related scales extending around the peripheral edges of the upper sector plate, the disc, and the lower sector plate, the scale of the upper sector plate being located inwardly of and adjacent to the disc scale, and the disc scale extending entirely around the disc, the scales on the sector plates having divisions similar to the divisions of the disc scale, said indicator arm having on its outer end inner and outer pointers referring respectively to the upper sector plate scale and the disc scale, said indicator arm having therein inner and outer sight openings, said upper sector plate having inner and outer arcs of sight openings respectively registrable with said inner and outer sight openings, said disc having thereon inner and outer rings divided into significant and distinct segments visible through sight openings of the indicator arm and of the upper sector plate when registered.
